# ContactsContract.Data

`public static final class ContactsContract.Data`
`extends Object` `implements ContactsContract.DataColumnsWithJoins`

java.lang.Object
↳ | android.provider.ContactsContract.Data

Constants for the data table, which contains data points tied to a raw contact. Each row of the data table is typically used to store a single piece of contact information (such as a phone number) and its associated metadata (such as whether it is a work or home number).

### Data kinds

Data is a generic table that can hold any kind of contact data. The kind of data stored in a given row is specified by the row's `ContactsContract.DataColumns.MIMETYPE` value, which determines the meaning of the generic columns `ContactsContract.DataColumns.DATA1` through `ContactsContract.DataColumns.DATA15`. For example, if the data kind is `CommonDataKinds.Phone`, then the column `ContactsContract.DataColumns.DATA1` stores the phone number, but if the data kind is `CommonDataKinds.Email`, then `ContactsContract.DataColumns.DATA1` stores the email address. Sync adapters and applications can introduce their own data kinds.

ContactsContract defines a small number of pre-defined data kinds, e.g. `CommonDataKinds.Phone`, `CommonDataKinds.Email` etc. As a convenience, these classes define data kind specific aliases for DATA1 etc. For example, `CommonDataKinds.Phone` is the same as `ContactsContract.Data`.

`ContactsContract.DataColumns.DATA1` is an indexed column and should be used for the data element that is expected to be most frequently used in query selections. For example, in the case of a row representing email addresses `ContactsContract.DataColumns.DATA1` should probably be used for the email address itself, while `ContactsContract.DataColumns.DATA2` etc can be used for auxiliary information like type of email address.

By convention, `ContactsContract.DataColumns.DATA15` is used for storing BLOBs (binary data).

The sync adapter for a given account type must correctly handle every data type used in the corresponding raw contacts. Otherwise it could result in lost or corrupted data.

Similarly, you should refrain from introducing new kinds of data for an other party's account types. For example, if you add a data row for "favorite song" to a raw contact owned by a Google account, it will not get synced to the server, because the Google sync adapter does not know how to handle this data kind. Thus new data kinds are typically introduced along with new account types, i.e. new sync adapters.

### Batch operations

Data rows can be inserted/updated/deleted using the traditional `ContentResolver#insert`, `ContentResolver#update` and `ContentResolver#delete` methods, however the newer mechanism based on a batch of `ContentProviderOperation` will prove to be a better choice in almost all cases. All operations in a batch are executed in a single transaction, which ensures that the phone-side and server-side state of a raw contact are always consistent. Also, the batch-based approach is far more efficient: not only are the database operations faster when executed in a single transaction, but also sending a batch of commands to the content provider saves a lot of time on context switching between your process and the process in which the content provider runs.

The flip side of using batched operations is that a large batch may lock up the database for a long time preventing other applications from accessing data and potentially causing ANRs ("Application Not Responding" dialogs.)

To avoid such lockups of the database, make sure to insert "yield points" in the batch. A yield point indicates to the content provider that before executing the next operation it can commit the changes that have already been made, yield to other requests, open another transaction and continue processing operations. A yield point will not automatically commit the transaction, but only if there is another request waiting on the database. Normally a sync adapter should insert a yield point at the beginning of each raw contact operation sequence in the batch. See `ContentProviderOperation.Builder#withYieldAllowed(boolean)`.

### Operations

Insert

  An individual data row can be inserted using the traditional `ContentResolver#insert(Uri, ContentValues)` method. Multiple rows should always be inserted as a batch.

  An example of a traditional insert:

       ContentValues values = new ContentValues();
       values.put(Data.RAW_CONTACT_ID, rawContactId);
       values.put(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE);
       values.put(Phone.NUMBER, "1-800-GOOG-411");
       values.put(Phone.TYPE, Phone.TYPE_CUSTOM);
       values.put(Phone.LABEL, "free directory assistance");
       Uri dataUri = getContentResolver().insert(Data.CONTENT_URI, values);

  The same done using ContentProviderOperations:

       ArrayList<ContentProviderOperation> ops =
                new ArrayList<ContentProviderOperation>();

       ops.add(ContentProviderOperation.newInsert(Data.CONTENT_URI)
                .withValue(Data.RAW_CONTACT_ID, rawContactId)
                .withValue(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE)
                .withValue(Phone.NUMBER, "1-800-GOOG-411")
                .withValue(Phone.TYPE, Phone.TYPE_CUSTOM)
                .withValue(Phone.LABEL, "free directory assistance")
                .build());
       getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);

Update

  Just as with insert, update can be done incrementally or as a batch, the batch mode being the preferred method:

       ArrayList<ContentProviderOperation> ops =
                new ArrayList<ContentProviderOperation>();

       ops.add(ContentProviderOperation.newUpdate(Data.CONTENT_URI)
                .withSelection(Data._ID + "=?", new String[]{String.valueOf(dataId)})
                .withValue(Email.DATA, "somebody@android.com")
                .build());
       getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);

Delete

  Just as with insert and update, deletion can be done either using the `ContentResolver#delete` method or using a ContentProviderOperation:

       ArrayList<ContentProviderOperation> ops =
                new ArrayList<ContentProviderOperation>();

       ops.add(ContentProviderOperation.newDelete(Data.CONTENT_URI)
                .withSelection(Data._ID + "=?", new String[]{String.valueOf(dataId)})
                .build());
       getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);

Query

  Finding all Data of a given type for a given contact

         Cursor c = getContentResolver().query(Data.CONTENT_URI,
                  new String[] {Data._ID, Phone.NUMBER, Phone.TYPE, Phone.LABEL},
                  Data.CONTACT_ID + "=?" + " AND "
                          + Data.MIMETYPE + "='" + Phone.CONTENT_ITEM_TYPE + "'",
                  new String[] {String.valueOf(contactId)}, null);

  Finding all Data of a given type for a given raw contact

         Cursor c = getContentResolver().query(Data.CONTENT_URI,
                  new String[] {Data._ID, Phone.NUMBER, Phone.TYPE, Phone.LABEL},
                  Data.RAW_CONTACT_ID + "=?" + " AND "
                          + Data.MIMETYPE + "='" + Phone.CONTENT_ITEM_TYPE + "'",
                  new String[] {String.valueOf(rawContactId)}, null);

  Finding all Data for a given raw contact
    Most sync adapters will want to read all data rows for a raw contact along with the raw contact itself. For that you should use the `RawContactsEntity`. See also `RawContacts`.

## Columns

Many columns are available via a `Data#CONTENT_URI` query. For best performance you should explicitly specify a projection to only those columns that you need.

Data
long | `BaseColumns._ID` | read-only | Row ID. Sync adapter should try to preserve row IDs during updates. In other words, it would be a bad idea to delete and reinsert a data row. A sync adapter should always do an update instead.
String | `ContactsContract.DataColumns.MIMETYPE` | read/write-once | The MIME type of the item represented by this row. Examples of common MIME types are: `CommonDataKinds.StructuredName` `CommonDataKinds.Phone` `CommonDataKinds.Email` `CommonDataKinds.Photo` `CommonDataKinds.Organization` `CommonDataKinds.Im` `CommonDataKinds.Nickname` `CommonDataKinds.Note` `CommonDataKinds.StructuredPostal` `CommonDataKinds.GroupMembership` `CommonDataKinds.Website` `CommonDataKinds.Event` `CommonDataKinds.Relation` `CommonDataKinds.SipAddress`
long | `ContactsContract.DataColumns.RAW_CONTACT_ID` | read/write-once | The id of the row in the `RawContacts` table that this data belongs to.
int | `ContactsContract.DataColumns.IS_PRIMARY` | read/write | Whether this is the primary entry of its kind for the raw contact it belongs to. "1" if true, "0" if false.
int | `ContactsContract.DataColumns.IS_SUPER_PRIMARY` | read/write | Whether this is the primary entry of its kind for the aggregate contact it belongs to. Any data record that is "super primary" must also be "primary". For example, the super-primary entry may be interpreted as the default contact value of its kind (for example, the default phone number to use for the contact).
int | `ContactsContract.DataColumns.DATA_VERSION` | read-only | The version of this data record. Whenever the data row changes the version goes up. This value is monotonically increasing.
Any type | `ContactsContract.DataColumns.DATA1` `ContactsContract.DataColumns.DATA2` `ContactsContract.DataColumns.DATA3` `ContactsContract.DataColumns.DATA4` `ContactsContract.DataColumns.DATA5` `ContactsContract.DataColumns.DATA6` `ContactsContract.DataColumns.DATA7` `ContactsContract.DataColumns.DATA8` `ContactsContract.DataColumns.DATA9` `ContactsContract.DataColumns.DATA10` `ContactsContract.DataColumns.DATA11` `ContactsContract.DataColumns.DATA12` `ContactsContract.DataColumns.DATA13` `ContactsContract.DataColumns.DATA14` `ContactsContract.DataColumns.DATA15` | read/write | Generic data columns. The meaning of each column is determined by the `ContactsContract.DataColumns.MIMETYPE`. By convention, `ContactsContract.DataColumns.DATA15` is used for storing BLOBs (binary data). Data columns whose meaning is not explicitly defined for a given MIMETYPE should not be used. There is no guarantee that any sync adapter will preserve them. Sync adapters themselves should not use such columns either, but should instead use `ContactsContract.DataColumns.SYNC1`-`ContactsContract.DataColumns.SYNC4`.
Any type | `ContactsContract.DataColumns.SYNC1` `ContactsContract.DataColumns.SYNC2` `ContactsContract.DataColumns.SYNC3` `ContactsContract.DataColumns.SYNC4` | read/write | Generic columns for use by sync adapters. For example, a Photo row may store the image URL in SYNC1, a status (not loaded, loading, loaded, error) in SYNC2, server-side version number in SYNC3 and error code in SYNC4.

Some columns from the most recent associated status update are also available through an implicit join.

Join with `StatusUpdates`
int | `ContactsContract.StatusColumns.PRESENCE` | read-only | IM presence status linked to this data row. Compare with `ContactsContract.ContactStatusColumns.CONTACT_PRESENCE`, which contains the contact's presence across all IM rows. See `StatusUpdates` for individual status definitions. The provider may choose not to store this value in persistent storage. The expectation is that presence status will be updated on a regular basis.
String | `ContactsContract.StatusColumns.STATUS` | read-only | Latest status update linked with this data row.
long | `ContactsContract.StatusColumns.STATUS_TIMESTAMP` | read-only | The absolute time in milliseconds when the latest status was inserted/updated for this data row.
String | `ContactsContract.StatusColumns.STATUS_RES_PACKAGE` | read-only | The package containing resources for this status: label and icon.
long | `ContactsContract.StatusColumns.STATUS_LABEL` | read-only | The resource ID of the label describing the source of status update linked to this data row. This resource is scoped by the `ContactsContract.StatusColumns.STATUS_RES_PACKAGE`.
long | `ContactsContract.StatusColumns.STATUS_ICON` | read-only | The resource ID of the icon for the source of the status update linked to this data row. This resource is scoped by the `ContactsContract.StatusColumns.STATUS_RES_PACKAGE`.

Some columns from the associated raw contact are also available through an implicit join. The other columns are excluded as uninteresting in this context.

Join with `ContactsContract.RawContacts`
long | `ContactsContract.RawContactsColumns.CONTACT_ID` | read-only | The id of the row in the `Contacts` table that this data belongs to.
int | `ContactsContract.RawContactsColumns.AGGREGATION_MODE` | read-only | See `RawContacts`.
int | `ContactsContract.RawContactsColumns.DELETED` | read-only | See `RawContacts`.

The ID column for the associated aggregated contact table `ContactsContract.Contacts` is available via the implicit join to the `RawContacts` table, see above. The remaining columns from this table are also available, through an implicit join. This facilitates lookup by the value of a single data element, such as the email address.

Join with `ContactsContract.Contacts`
String | `ContactsContract.ContactsColumns.LOOKUP_KEY` | read-only | See `ContactsContract.Contacts`
String | `ContactsContract.ContactsColumns.DISPLAY_NAME` | read-only | See `ContactsContract.Contacts`
long | `ContactsContract.ContactsColumns.PHOTO_ID` | read-only | See `ContactsContract.Contacts`.
int | `ContactsContract.ContactsColumns.IN_VISIBLE_GROUP` | read-only | See `ContactsContract.Contacts`.
int | `ContactsContract.ContactsColumns.HAS_PHONE_NUMBER` | read-only | See `ContactsContract.Contacts`.
int | `ContactsContract.ContactOptionsColumns.STARRED` | read-only | See `ContactsContract.Contacts`.
String | `ContactsContract.ContactOptionsColumns.CUSTOM_RINGTONE` | read-only | See `ContactsContract.Contacts`.
int | `ContactsContract.ContactOptionsColumns.SEND_TO_VOICEMAIL` | read-only | See `ContactsContract.Contacts`.
int | `ContactsContract.ContactStatusColumns.CONTACT_PRESENCE` | read-only | See `ContactsContract.Contacts`.
String | `ContactsContract.ContactStatusColumns.CONTACT_STATUS` | read-only | See `ContactsContract.Contacts`.
long | `ContactsContract.ContactStatusColumns.CONTACT_STATUS_TIMESTAMP` | read-only | See `ContactsContract.Contacts`.
String | `ContactsContract.ContactStatusColumns.CONTACT_STATUS_RES_PACKAGE` | read-only | See `ContactsContract.Contacts`.
long | `ContactsContract.ContactStatusColumns.CONTACT_STATUS_LABEL` | read-only | See `ContactsContract.Contacts`.
long | `ContactsContract.ContactStatusColumns.CONTACT_STATUS_ICON` | read-only | See `ContactsContract.Contacts`.

## Constants

### CONTENT_TYPE

    public static final String CONTENT_TYPE

The MIME type of the results from `CONTENT_URI`.

Constant Value: "vnd.android.cursor.dir/data"

### EXTRA_ADDRESS_BOOK_INDEX

    public static final String EXTRA_ADDRESS_BOOK_INDEX

Add this query parameter to a URI to get back row counts grouped by the address book index as cursor extras. For most languages it is the first letter of the sort key. This parameter does not affect the main content of the cursor.

     Example:

     import android.provider.ContactsContract.Contacts;

     Uri uri = Contacts.CONTENT_URI.buildUpon()
              .appendQueryParameter(Contacts.EXTRA_ADDRESS_BOOK_INDEX, "true")

              null, null, null);
     Bundle bundle = cursor.getExtras();
     if (bundle.containsKey(Contacts.EXTRA_ADDRESS_BOOK_INDEX_TITLES) &&
             bundle.containsKey(Contacts.EXTRA_ADDRESS_BOOK_INDEX_COUNTS)) {
         String sections[] =
                 bundle.getStringArray(Contacts.EXTRA_ADDRESS_BOOK_INDEX_TITLES);
         int counts[] = bundle.getIntArray(Contacts.EXTRA_ADDRESS_BOOK_INDEX_COUNTS);
     }

Constant Value: "android.provider.extra.ADDRESS_BOOK_INDEX"

### EXTRA_ADDRESS_BOOK_INDEX_COUNTS
